- 2. Description of the Background of the Invention
- Multiple different volatile material dispensers are commercially sold and generally include a housing and a volatile material refill that is inserted into the housing. The refill generally includes a container or bottle for holding a volatile material therein. In some dispensers, the volatile material is passively emitted therefrom. In other dispensers, a diffusion element is utilized to facilitate the dispensing of the volatile material. Examples of diffusion elements include heaters, piezoelectric elements, fans, aerosol actuators, and the like. Regardless of the manner in which the volatile material is emitted, once the volatile material has been expended from the refill, the refill can typically be removed by a user and replaced with a new refill.
- One type of commercial volatile material dispenser, referred to herein as a plug-in scented oil dispenser, includes a housing and a heater disposed within the housing. A refill for use with a plug-in scented oil dispenser generally includes a container portion having a bottom end and a top end, wherein the container portion terminates in a neck portion at the top end. A volatile material is disposed within the container portion and a wick is in contact with the volatile material and extends out of the refill through the neck portion. A plug or other connector generally positions and retains the wick within the neck portion. A cap covers the wick and the neck portion and may be removed before the container is inserted into the dispenser. Upon insertion of the refill into the dispenser, at least a portion of the wick is disposed adjacent the heater such that volatile material that moves through the wick is volatilized by the heater.
- Another feature of various volatile material dispensers is a retention mechanism. Generally, a refill will have a shape and size complementary to the dimensions of the dispenser housing, and many dispenser housings have mechanisms designed to securely retain a refill container within the housing. Some of the retention mechanisms may only work properly with specific refill containers that exhibit certain structural features.
- According to one aspect of the present invention, a refill for a volatile material dispenser comprises a container having a neck portion. A wick is in contact with a volatile material in the container and extends out of the neck portion. A structure is disposed on an outer surface of the neck portion for attachment of a cap thereto. The structure is also adapted to interact with latches disposed in a volatile material dispenser to retain the refill therein, and the container is devoid of an additional retaining structure on the neck portion thereof.
- According to another aspect of the present invention, a method of inserting a refill into a volatile material dispenser includes the step of providing a volatile material dispenser. The method further includes the step of providing a refill having a container, a neck portion, a wick in contact with volatile material in the container and extending out the neck portion, an annular member disposed on an outer surface of the neck portion, and a cap attached to the neck portion by the annular member. Additionally, the method includes the step of removing the cap and inserting the refill into the dispenser such that at least one latch in the dispenser grasps the annular member on the neck portion of the container and retains the container therein.
- According to a further aspect of the present invention, a method of inserting a refill into a volatile material dispenser includes the step of providing a volatile material dispenser with at least one latch. The method further includes the step of providing a refill having a container with volatile material, a wick in contact with the volatile material and extending out a neck portion of the container, and a cap disposed over the wick and connected to a n annular member disposed on the neck portion. Additionally, the method includes the steps of disconnecting the cap from the refill and inserting the refill into a cavity formed within the volatile material dispenser such that the at least one latch engages the annular member to retain the container therein. The neck portion of the refill is devoid of any other structure that functions to retain the refill.

FIGS. 1-5 illustrate arefill 10 according to one embodiment of the present invention. Therefill 10 generally includes acontainer portion 12 that holds a volatile material, wherein a generallycylindrical neck portion 14 extends upwardly from thecontainer portion 12. Aplug assembly 16 is disposed within and attached to theneck portion 14 of therefill 10. Awick 18 is disposed in contact with the volatile material inside thecontainer portion 12 and extends upwardly through theneck portion 14, such that a portion of thewick 18 may he exposed to a surrounding environment. Thewick 18 is retained within theneck portion 14 by theplug assembly 16. Acap 20, as seen inFIGS. 5 and 6 , may be threaded onto theneck portion 14 and disposed over thewick 18 and plugassembly 16 during shipment and storage thereof, as discussed in greater detail hereinafter. - The
container portion 12 includes front andrear surfaces rear surfaces FIGS. 1 and 4 , thefront surface 22 a has a generally bulbous central portion and is generally curved inwardly at sides and a bottom thereof and therear surface 22 b is generally planar. Further, as seen inFIGS. 2 and 3 , the side surfaces 22 c, 22 d begin at theneck portion 14 and curve outwardly attop portions 27 thereof and inwardly atbottom portions 28 thereof to generally form a heart shape that is truncated at abottom surface 29 thereof. - A shell-shaped
protrusion 30 extends outwardly from thefront surface 22 a and a semi-cylindrical projection 32 extends outwardly from therear surface 22 b along a height H (FIG. 4 ) of thecontainer portion 12. Referring toFIG. 4 , the front andrear surface neck portion 14. In particular, thefront surface 22 a is spaced a distance D1 from the centerpoint 34 and therear surface 22 b is spaced a distance D2 from the centerpoint 34, wherein D1 is greater than D2. - Although the
container portion 12 is depicted herein as having a particular size, shape, and configuration, the size, shape, and/or configuration of thecontainer portion 12 may be varied without departing from the scope of the present invention. - As noted above, the
plug assembly 16 is attached to theneck portion 14 of therefill 10 and surrounds and retains thewick 18. As best seen inFIGS. 5 and 6 , theplug assembly 16 includes aretention portion 38 that snaps onto theneck portion 14 of therefill 10 and asheath portion 40 that extends upwardly from theretention portion 38 and surrounds thewick 18. Thesheath portion 40 extends around a majority of a portion of thewick 18 that extends out of therefill 10, leaving atop portion 41 of thewick 18 exposed. - As best seen in
FIGS. 1 , 2, and 6, athread 42 extends outwardly from anouter surface 43 of theneck portion 14 of therefill 10 to interact with and retain thecap 20. Thethread 42 spirals down around theneck portion 14 of therefill 10 and engages a similarly shaped threaded groove 44 (FIG. 6 ) in thecap 20 to retain thecap 20 thereon. Thethread 42 includes anupper end 46 that spirals down around theneck portion 14 of therefill 10 and terminates at alower end 48 of thethread 42. Both upper and lower thread ends 46, 48 are disposed on afront portion 50 of theneck portion 14. Optionally, the upper and lower thread ends 46, 48 may be disposed at a different position on theneck portion 14 and/or may be disposed at positions different from one another. As can be seen fromFIGS. 1-3 , thethread 42 extends a little more than 360 degrees around theneck portion 14 of therefill 10. Thethread 42 preferably extends between about 180 degrees and about 1440 degrees about theneck portion 14, more preferably extends between about 270 degrees and about 450 degrees about theneck portion 14, and most preferably extends about 360 degrees about theneck portion 14. Athread 42 extension of at least 180 degrees is necessary to insure proper placement of thetop portion 41 of thewick 18 with respect to a heater disposed in a dispenser, but an extension of 360 is preferable to insure proper placement of thetop portion 41 of thewick 18 andconsistent refill 10 height placement. If multiple threads are disposed on theneck portion 14, multiple attachment areas are provided. Referring toFIGS. 2 and 5 , thethread 42 includes a number ofvoids 60 therein, wherein the voids allow therefill 10 to interact with attachment mechanisms in one or more dispensers without interference therewith. Although twovoids 60 are depicted, any number ofvoids 60 or no voids may be utilized. As is evident fromFIGS. 1-6 , theneck portion 14 of therefill 10 is devoid of any other projections, annular members, or other features thereon that would allow therefill 10 to be retained within a volatile material dispenser. - Although the
thread 42 is shown as continuous, thethread 42 may alternatively be discontinuous, as depicted inFIGS. 7 and 8 . In particular, therefill 10 ofFIGS. 7 and 8 is identical to therefill 10 ofFIGS. 1-6 , except for a thread 62 thereof. The thread 62 includes a gap or void 64 therein and also starts and begins at positions different from the thread 42 (the thread 62 start and end points 65 a, 65 b are offset to the left of a central axis 66 of the refill 10). The thread 62 may extend about theneck portion 14 of therefill 10 ofFIGS. 7 and 8 the same distances as detailed with respect to thethread 42. The gap 64 in the thread 62 provides a manner to more evenly hold therefill 10 in place. Specifically, as can be seen, the thread 62 is spiral in nature and one side of the thread 62 is higher than an opposing side of the thread 62. If, for example, opposing latches (see latches in relation toFIG. 11 ) are utilized, a first of the latches would abut theneck portion 14 at the gap 64 to provide a friction fit therebetween and a second of the latches would hook under and retain the thread 62 at a point opposite the gap 64. The gap 64 allows abutment of the latch at a point directly opposite the thread 62 (at the same vertical position), rather than above or below such latch 62. Otherwise, it is possible in some situations, that opposing latches would grasp and retain portions of the thread 62 opposite one another that are at different vertical positions, thereby causing therefill 10 to be tilted. - Although
threads 42, 62 are utilized herein to retain thecap 20 on therefill 10 and retain therefill 10 within a dispenser, other structures may be utilized. For example, in a further embodiment as seen inFIG. 9 , a non-spiraled, annular snap 67 a is disposed on theneck portion 14 of therefill 10 with a small gap 67 b between ends thereof and a groove 68 is disposed around an entire inner surface of thecap 20. Thecap 20 optionally includes a projection 69 extending from the inner surface thereof, wherein the projection 69 must be aligned with the gap 67 b in the annular snap to remove thecap 20 from therefill 10. As with previous embodiments, the annular snap 67 a would also serve to retain therefill 10 within a dispenser. Other types of annular snaps are possible, wherein the annular snap extends between about 180 degrees and about 360 degrees about theneck portion 14 of therefill 10. For example, in a further embodiment similar to that ofFIG. 9 , the annular snap 67 a extends 360 degrees around theneck portion 14 and the projection 69 is removed. Still optionally, one or more continuous or discontinuous projections that snap fit with the annular snap may be disposed on an inner surface of the cap. Again, the annular snap also retains therefill 10 within a dispenser. -
FIGS. 10 and 11 illustrate onevolatile material dispenser 70 that accepts and retains therefill 10. Thedispenser 70 includes ahousing 71 having anupper portion 76 and alower portion 78. A semi-cylindrical shapedgroove 80 is disposed in thelower portion 78 of thedispenser 70 and acavity 82 is formed within theupper portion 76 of thedispenser 70, wherein a refill, such as therefill 10, may be inserted into and retained within thecavity 82. Achannel 83 is disposed within an upper portion of thecavity 82 and a set of opposingresilient latches 84 a, 84 b is also disposed within a lower portion of thecavity 82. A heater (not shown) is generally disposed adjacent thechannel 83 for heating a wick disposed within thechannel 83, as discussed in greater detail hereinafter. - Before use of the
refill 10, thecap 20 is unthreaded and removed from theneck portion 14 of therefill 10. After thecap 20 is removed, therefill 10 may be inserted into a dispenser, such as thedispenser 70 ofFIGS. 10 and 11 , by inserting thetop portion 41 of thewick 18 into thechannel 83 formed within thecavity 82 of thedispenser 70 and moving therefill 10 into thedispenser 70. As therefill 10 is inserted, the semi-cylindrical projection 32 rides within the similarly-shapedgroove 80 in thelower portion 78 of thedispenser 70 and thewick 18 moves further into thechannel 83. Eventually, thethread 42 interferes with the opposingresilient latches 84 a, 84 b disposed within the lower portion of thecavity 82. Thethread 42 pushes the resilient latches 84 a, 84 b outwardly until thethread 42 passes thelatches 84 a, 84 b. Once thethread 42 passes thelatches 84 a, 84 b, thelatches 84 a, 84 b return to their original position, such that when gravity acts on therefill 10, thethread 42 interferes with the opposingresilient latches 84 a, 84 b to prevent downward movement of therefill 10. In particular, as seen inFIG. 11 , when thelatches 84 a, 84 b are in a resting position, a distance D3 between innermost points of thelatches 84 a, 84 b is less than a distance D4 between outermost edges of thethread 42. Therefill 10 may be removed from thedispenser 70 by pulling downwardly on therefill 10, which thereby pushes outwardly on thelatches 84 a, 84 b to allow removal of therefill 10. By using thesame thread 42 to both retain thecap 20 on therefill 10 and retain therefill 10 within the dispensingdevice 70, manufacturers may save time, money, and material. - While particular elements, embodiments, and applications of the present invention have been shown and described, it is understood that the invention is not limited thereto because modifications may be made by those skilled in the art, particularly in light of the foregoing teaching. It is therefore contemplated by the appended claims to cover such modifications and incorporate those features which come within the spirit and scope of the invention.
- Many contemporary refills use at least one retention mechanism to retain the cap on the refill and at least one additional and separate retention mechanism to retain the refill within the dispenser. However, the present invention uses just one retention mechanism to retain both the cap on the refill and the refill within the dispensing device. Thus, the present invention saves time, money and material in the manufacturing process by reducing the number of necessary parts.
- Numerous modifications to the present invention will be apparent to those skilled in the art in view of the foregoing description. Accordingly, this description is to be construed as illustrative only and is presented to enable those skilled in the art to make and use the disclosure and to teach the best mode of carrying out same. The exclusive rights to all modifications that come within the scope of the appended claims are reserved.
